It’s been teased and now it’s been confirmed by director Zack Snyder: The first preview for Batman v Superman: Dawn of Justicewill debut on April 20 only in IMAX theaters at a “special teaser screening event” that will also include an introduction from Snyder. On Twitter, Snyder revealed exactly how to attend the event, and gave a brief taste of what’s to come:

According to the rumors, Snyder’s announcement of this unusual event would include just five seconds of the Batman v Superman teaser, but the actual tweet featured about 20 seconds. That doesn’t sound like much, but it’s four times as much as we were supposed to get. It was almost half a minute of Batman v Superman! Okay, so it was basically just two shots of the characters’ costumes. But it was two shots of the characters’ costumes! Okay fine, I got nothing.

If you want to see the whole teaser plus Snyder’s intro, you’ll need to register at the film’s official site. They’ll give you the theaters playing the preview in your area then redirect you to Warner Bros.’ site, where you’ll need to register an account and then click through a bunch of forms before you get your actual passes (up to two) to the event. Space is limited, so you’ll want to arrive early, or you’ll miss out on literally dozens of seconds from Batman v Superman, which opens in theaters on March 25, 2016.
